John Nichols, associate editor for The Capital Times and correspondent for "The Nation," and Christian Schneider, columnist for The Milwaukee Journal-Sentinel discuss who will win key primary races and why.

Walker’s campaign against likely Democratic challenger Mary Burke has included ads highlighting outsourcing by Trek Bicycle, while Republicans have frequently criticized her personal wealth. Johnson characterized the approach as “demonizing success,” but told “UPFRONT with Mike Gousha” he believes Walker has improved the business environment in the state.

“I think every elected official really ought to concentrate on trying to make … an attractive place for business,” Johnson said on the program, produced in partnership with WisPolitics.com.

The Republican senator made further headlines for his continued effort to sue President Barack Obama over what he asserts are illegal health care benefits extended to congressional staff. He plans to appeal the dismissal of his lawsuit, saying he aims to use the litigation to highlight the expansion of executive powers.

According to Johnson, the Senate Ethics Committee will allow him to use campaign funds to finance the appeal.

Johnson also blamed Obama’s use of executive orders for the flood of children at the nation’s southern border, saying deferred action on deportation is responsible for encouraging more illegal immigration.

According to Nichols, the Democratic primary for attorney general may be determined by last-minute spending. He said Jefferson County District Attorney Susan Happ has substantial resources to finance a TV campaign that could overwhelm the grass roots efforts of opponent state Rep. Jon Richards, D-Milwaukee.

In the race for Wisconsin’s 6th Congressional District, Schneider said the temperament of the candidates is likely to factor heavily in the outcome of the Republican primary. He said Rep. Duey Stroebel’s efforts to weaken his opponents may backfire, but said the otherwise “perfect” candidate, state Sen. Joe Leibham of Sheboygan, could see his lead diminish as a result of his opponents’ criticisms.

Schneider said state Sen. Glenn Grothman’s prospects may suffer because of his occasionally contentious relationship with GOP leaders in the state.

“There’s nobody smarter, or more conservative, or harder working in the state Legislature than Glenn Grothman.” Schneider said. “But there’s also nobody as … prone to go off message.”

Nichols suggested the primary against incumbent Milwaukee County Sheriff David Clarke could make headlines on Wednesday if challenger Chris Moews, a lieutenant with the Milwaukee Police Department, wins. He said the potential Clarke ouster depends on a new generation of African-American legislators like Rep. Mandela Barnes energizing constituents to vote for changes at the Sheriff’s Department.
